Answer:
your wrong lol im sry btw this is a alt XDDD
Step-by-step explanation:
Given that the problem does not specify if
y is <span>opposite, adjacent or hypotenuse side, I will provide two solutions to this problem.
Case 1. Y is the hypotenuse side. (See figure 1)
According to the Pythagorean Theorem, for a right triangle, it is true that:
</span>
<span>
being c the hypotenuse side and a and b the opposite and adjacent side respectively. So, for the figure 1 it is true that:
</span><span>
z = a = 15cm
x = b = 9cm
y = c = ?
</span>
∴
Case 2. Y is the opposite side (The same happens as if it were the adjacent side). (See figure 2)
From the equation:
For the figure:
y = a = ?
x = b = 9cm
z = c = 15cm
We need to isolate a, so:
∴
Answer:
The z-score is 2.5106 which is an unusual value of z-score as it is greater than 2.00
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 161 pounds
Standard Deviation, σ = 23.5 pounds
x = 220 pounds
Formula:
Putting values, we get,
Thus, the z-score is 2.5106 which is an unusual value of z-score as it is greater than 2.00

Step-by-step explanation:
<u>Step 1: Define</u>
5x - 6 = 4x - 12
<u>Step 2: Solve for </u><em><u>x</u></em>
- Isolate <em>x</em> terms: x - 6 = -12
- Isolate <em>x</em>: x = -6
180 divided by 3 which is 60 then multiply by 4 then you get 240
180/3=60 60x4=240
so the original price of the item is $240
